Description

Technical Field

[0001] This utility model relates to the field of stacking machine technology, specifically a novel stacking mechanism. Background Technology

[0002] As is well known, a pallet feeder is an important piece of equipment at the front end of an automated production line or logistics line. It is installed next to the pallet warehouse and uses devices such as lifting mechanisms, pushers, suction cups or rollers to separate the bottom or frontmost pallet from the pallet above.

[0003] For example, the invention patent with application publication number CN117142111A, application publication date December 1, 2023, entitled "A Pallet Feeding Machine," includes a frame and a control box installed outside the frame. The frame consists of a first support beam, a second support beam, vertical beams, and horizontal beams. The vertical beams and horizontal beams are equipped with material gripping mechanisms. Each material gripping mechanism includes a mounting frame on the front of the two vertical beams, a hydraulic cylinder fixedly installed inside the horizontal beam, a first mounting seat and a second mounting seat on the side of the mounting frame away from the vertical beams, and a dual-axis cylinder. The two second support beams are equipped with a conveying mechanism for placing materials. The top of the vertical plate is equipped with a correction mechanism that works in conjunction with the conveying mechanism to transport materials. This pallet feeding machine, through the installation of buffer plates and buffer components, ensures the stability of the pallet's descent, reduces vibration during material feeding, prevents wooden pallets from easily deforming or breaking, and avoids irregular stacking shapes. Combined with the correction mechanism, it corrects material deviation, making pallet conveying smoother.

[0004] The shortcoming of the existing technology is that the teeth of the stacking machine are inserted from both sides of the pallet and then the pallet is lifted up. However, when this stacking machine is working, the space on both sides of the stacked pallets needs to be cleared so that the teeth can move to both sides of the pallet and then insert into the slots on the pallet. However, most of the pallets in the pallet library are stacked tightly, and it is difficult to have enough space on both sides of the pallet for the teeth to enter. Utility Model Content

[0005] The purpose of this invention is to provide a novel stacking mechanism to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel stacking mechanism, comprising a frame, wherein a mounting plate is provided at the top of the frame and located in the middle, and a guide frame that moves vertically is movably provided on the side wall of the mounting plate, and inserting teeth that move horizontally to insert into the stacking plate slot are symmetrically slidably provided on the guide frame, the ends of the inserting teeth extending from below the mounting plate to the opposite side of the guide frame.

[0007] As a further description of the above technical solution: a mounting frame is slidably disposed in the guide frame, and a pair of tenons extending into the interior of the mounting frame are disposed on the insert teeth.

[0008] As a further description of the above technical solution: the inside of the guide frame is symmetrically provided with a first guide rail for guiding the movement of the installation frame.

[0013] As a further description of the above technical solution: a support plate is provided at the bottom of the insert tooth, the support plate is arc-shaped and its top is tangent to the bottom surface of the insert tooth.

[0014] As a further description of the above technical solution: a pair of tenons on the insert teeth are each provided with a screw between them and the support plate.

[0015] As a further description of the above technical solution: the interior of the mounting frame is symmetrically provided with guide rods that penetrate through the two pairs of tenons.

[0016] In the above technical solution, the novel stacking mechanism provided by this utility model has the following beneficial effects: During operation, the guide frame moves vertically relative to the mounting plate, so that the insert teeth on the guide frame are aligned with the insert teeth on the second pallet below.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a novel stacking mechanism, including a frame 2, with a mounting plate 1 located in the middle at the top of the frame 2, and a guide frame 11 that moves vertically on the side wall of the mounting plate 1. The guide frame 11 has symmetrically sliding insert teeth 13 that move horizontally to insert into the stack slots, and the ends of the insert teeth 13 extend from below the mounting plate 1 to the opposite side of the guide frame 11.

[0026] Specifically, during operation, the guide frame 11 moves vertically relative to the mounting plate 1, aligning the insert teeth 13 on the guide frame 11 with the insert teeth 13 on the second pallet below. Then, the insert teeth 13 move laterally and insert into the slots on the pallet. The guide frame 11 moves vertically upward with the insert teeth 13, lifting the upper pallet and leaving only the bottom pallet, which is convenient for the pallet to participate in the automated production line. After the pallet leaves, the guide frame 11 moves downward and puts the pallet down, and the insert teeth 13 separate from the pallet. This device only requires space on one side of the stacked pallets to lift them, and the pallets supported by the guide frame 11 and the insert teeth 13 are positioned on both sides of the mounting plate 1, which helps to balance the pressure of the entire device and reduce the device from tilting due to excessive weight of the pallets.

[0027] Furthermore, in the above embodiments, the frame 2 can be fixed on the ground or fixed on a movable base to facilitate the device in supporting the moving pallet.

[0028] In another embodiment of the present invention, a mounting frame 12 is slidably disposed in the guide frame 11, and a pair of tenons 131 extending into the mounting frame 12 are disposed on the insert 13.

[0029] Specifically, the tenon 131 securely connects the insert 13 to the mounting frame 12, and the tenon 131 moves along the mounting frame 12 to change the position of the insert 13 so that the insert 13 is aligned with the slot on the pallet.

[0030] In another embodiment of the present invention, a first guide rail 111 for guiding the movement of the mounting frame 12 is symmetrically arranged inside the guide frame 11, and a timing belt 114 is movably arranged on the guide frame 11, and the mounting frame 12 is fixedly connected to the timing belt 114.

[0031] Specifically, a motor and pulley for driving the synchronous belt 114 are provided on the side of the guide frame 11 away from the mounting plate 1. The weight of the motor and pulley can balance the pressure on the toothed gear 13 during the lifting of the pallet, thus maintaining the overall balance of the device.

[0032] Furthermore, during operation, the motor drives the pulley to move, and the pulley drives the mounting frame 12 fixedly mounted on the timing belt 114 via the timing belt 114, so that the mounting frame 12 moves horizontally along the first guide rail 111, thereby driving the inserter 13 to move laterally and insert into the slot on the pallet to support the pallet.

[0033] In another embodiment of the present invention, the mounting plate 1 is provided with a second guide rail 112 on the side walls on opposite sides for guiding the guide frame 11 to move in the vertical direction.

[0034] Specifically, the mounting plate 1 has symmetrically distributed third guide rails 113 on its side wall near the guide frame 11.

[0035] Furthermore, the second guide rail 112 cooperates with the guide rail to guide the guide frame 11 to move in the vertical direction, and the groove on the guide frame 11 that fits with the second guide rail 112 and the third guide rail 113 can also resist the sagging of the guide frame 11 under the action of the material strength of the guide frame 11 itself, so that the guide frame 11 remains in a horizontal state.

[0036] In another embodiment of the present invention, a counterweight 117, a sprocket 115, and a transmission chain adapted to the sprocket 115 are movably disposed on the side wall of the mounting plate 1. One end of the transmission chain is fixedly installed on the guide frame 11, and the other end is fixedly installed on the counterweight 117.

[0037] Specifically, the mounting plate 1 is provided with a chain 116 for driving the sprocket 115 to rotate. The counterweight 117 is vertically slidably mounted on the side wall of the mounting plate 1. Under the action of gravity, the counterweight 117 pulls the transmission chain, so that the transmission chain and the sprocket 115 are tightly engaged, so that the sprocket 115 drives the guide frame 11 to move through the transmission chain.

[0038] Furthermore, when it is necessary to lift the bottom pallet, the inserter 13 is inserted into the slot on the pallet, the motor drives the sprocket 115 to rotate, the sprocket 115 drives the transmission chain to move, the transmission chain drives the guide frame 11 and the inserter 13 to move upward, thereby causing the inserter 13 to lift the pallet to move upward.

[0039] In another embodiment of the present invention, a support plate 132 is provided at the bottom of the insert 13. The support plate 132 is arc-shaped and its top is tangent to the bottom surface of the insert 13. A screw 133 is provided between a pair of tenons 131 on the insert 13 and the support plate 132.

[0040] Specifically, the support plate 132 is fixed to the tenon 131 by the screw 133, and the arc-shaped support plate 132 supports the insert tooth 13, improves the strength of the insert tooth 13, and reduces the possibility of the insert tooth 13 bending downward. The position of the support plate 132 near the end of the insert tooth 13 is close to the bottom surface of the insert tooth 13, so it will not hinder the insert tooth 13 from being inserted into the slot on the pallet. It also transmits part of the pressure on the insert tooth 13 during the process of lifting the pallet to the left side of the mounting plate 1, balances the forces on both sides of the mounting plate 1 to ensure the overall balance of the device and avoids tilting.

[0041] In another embodiment of the present invention, guide rods 121 that penetrate two pairs of tenons 131 are symmetrically arranged inside the mounting frame 12.

[0042] Specifically, the tenon 131 has a through hole that matches the guide rod 121. The tenon 131 can move along the guide rod 121 with the insert 13 to adjust the position of the insert 13 so that the insert 13 is aligned with the slot on the pallet.

[0043] Furthermore, in the above embodiment, the guide rod 121 can be a threaded rod. The two guide rods 121 are respectively coupled to a tenon 131 on the two insert teeth 13. The mounting frame 12 is provided with a stepper motor for driving the guide rods 121 to rotate. The two stepper motors drive the two guide rods 121 to rotate, and the guide rods 121 drive the two tenons 131 to move, thereby adjusting the position of the two insert teeth 13 so that the insert teeth 13 can be aligned with the slots on the pallet.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
